Читать книгу Overhead Distribution Lines - Lawrence M. Slavin - Страница 8

This manual provides a general overview of the use of utility distribution poles for electric supply and communication applications. The intended audience includes utility engineers as well as those without a technical background, but who desire an understanding of the principles and various issues related to their application. The book is more an introduction to the subject than a detailed design, installation, or operations handbook and is not a replacement for the normal training and experiences typically required for either power or communications engineers responsible for the design, operation, and maintenance of overhead lines. This manual is a compendium of practical engineering and design information for poles and supported facilities, enhanced with some technical details that are not readily available elsewhere, that will prove to be helpful in some utility applications. The book is not intended to cover construction practices, which items are appropriately covered elsewhere, such as The Lineman's and Cableman's Handbook and the Telcordia Blue Book – Manual of Construction Procedures.

Information is provided on the physical characteristics of various types of utility poles, overhead supply and communication wires and cables, joint-use issues and related safety rules, including national standards and other related documents. The single most relevant document is the National Electrical Safety Code (NESC^®), which is adopted or reflected in various regulations or industry practices throughout most of the United States and its territories. Other relevant documents include national standard ANSI O5.1 Wood Poles: Specifications and Dimensions and as well as various ASCE manuals, and documents produced by the Rural Utilities Service (RUS). The State of California is unique in that it has produced its own rules prescribed for overhead lines under the jurisdiction of its Public Utilities Commission, General Order No. 95 Rules for Overhead Electric Line Construction.

It was the original intention that this manual be published to include any new information contained in the upcoming (2022) edition of the NESC. However, the possible delayed availability of this edition, resulting from the COVID-19 pandemic, suggested that it would be more beneficial to base the manual on the current (2017) edition of the NESC, presented in a manner consistent with the publically available Pre-Print for the 2022 edition, rather than delay the publication of this manual. It is also recognized that, in most cases, based on the “grandfather” clause of the NESC, any new rules would only be applicable to newly constructed pole lines.

The information in this document is believed to be accurate at the time of its preparation, but is provided without any warranty, expressed or implied.
